WILLIAM IRA HARGRODER, OF CHURCH POINT, LOUISIANA.

HARROW.

SPECIFICATION formmg part of Letters Patent No. 361,284, dated April 19,1887.

Application filed January 28, 1887. Serial No. 225,799. (No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM IRA IIARGRO DER, a citizen of the UnitedStates, residing at Church Point, in the parish'of St. Landry and-Stateof Louisiana, have invented a new and useful Improvement in Harrows, ofwhich the following is a specification.

My invention relates to an improvement in harrows; and it consists in acertain novel construction and arrangement of parts, fully set forthhereinafter, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a top plan view of my improvedharrow. Fig. 2 is a central longitudinal section thereof, and Fig. 3 isa front elevation thereof.

Referring to the drawings, in which similar letters denote correspondingparts in all the figures, Ais a triangular barrow-frame consisting ofthe rear cross-bar, B, and the 0011- verging side bars, 0, to all threeof which bars are secured the depending narrow-teeth D.

E is a central draft-beam secured at its front end between the frontends of the side bars, 0, and at the rear end tothe center of thecross-bar B, to the center of which draft-beam are secured the frontends of the plow-handles F, having the usual braces, G, the lower endsof which are secured to the rear end of the said draft-beam.

H is a plow-standard secured to the draftbeam E, near the rear endthereof, and, curving over the cross-bar B, is provided on its lower endwith the cultivating-shovel I.

To the front of the central draft-beam, E, which projects a shortdistance beyond the apex of the triangular barrow-frame, is secured adownwardly and forwardly extending standard,K, having the blizzard-wingor sweep L attached thereto. Said buzzard wing or sweep consists of thewide-spreading arms M, converging to a point'in front of the standard L,and having the free outer or rear ends thereof on a level with thepoint. The point at the front of the blizzard-wing is set somewhat-lower down than the barrow-teeth, and the front edges of the arms M arecomparatively sharp.

N is a vertical guide-post, also secured to the front projecting end ofthe draft-beam E and having the vertical slot 0, in the sides of whichpost are a series of transverse aligned openings, P, adapted to receivethe bolt R.

S is the draft-chain, which passes through the guide-post N under thebolt R, and is se cured at the rear end to the draft-beam EJoy means ofthe link T, the perforated ends of which are placed on either side ofthe draftbeam and pivotally secured thereto by the bolt U, passingthrough said perforated ends and one of the transverse openings V in thesaid draft-beam.

The function of the buzzard-wing is to clear the surface of the soil ofall grass and weeds, and its mode of operation is to cut down in thesoil under the grass and throw it out, whereupon the barrow-teeth,following closely after the blizzard-wing, break the clods and leave asmoothfine surface. The plow-shovel I is to be used only in the sowingseason to form a furrow to sow the seed in. At other times the standardmay be detached from the draft-beam, to which it is merely bolted.

The depth to which the blizzard-wing cuts may be regulated by adjustingthe bolt R in the aligned openings Pin the guide-post N, it beingobvious that the higher the said bolt is placed the deeper thebuzzard-wiug will out.

It will readily be seen that by attaching the draft-chain to thedraft-beam some distance behind the front thereof, I am able to make useof the weight of the fore part of the ma chine to hold the buzzard-wingdown to the work. This is of advantage, also, in an ordinary harrow, aswhen the draft chain or pole is secured to the front of the machine thedraft-animals have a tendency to lift the said fore part and prevent theproper working thereof.

I provide a central draft, which will materially assist the properworking of the parts.

Having thus described the construction and operation of my invention,what I claim, and desire to secure by Letters Patent of the UnitedStates, is-- 1. In a harrow, the combination of the toothed frame havinga central longitudinal draft-beam, a depending standard at the front endof the frame, a wing or sweep, L, carried by the standard andextending'laterally therefrom, and a draft-chain connected to thedraftbeam atan intermediate 'point of its length and passing through aguide on the frame, as

and for the purpose set forth.

2. In a barrow, the frame A, central draft beam, E, and buzzard-wing -orsweep L, combined with the draft-chain S, attachable to the saiddraft-beam at any point between the center and front end thereof, andheld from side motion by the vertical post N, in which the said chain isvertically adjustable, substau tially as described, for the purpose setforth.

3. In a harrow, the triangular harrow-frame A, the central draft-beam,E, handles F, buzzard-wing 0r sweep L, attached to the front
